From: Bjorn Helgaas <bhelgaas@google.com> MSI/MSI-X init was a little unconventional. We had pci_msi_setup_pci_dev() to disable MSI and MSI-X, in probe.c instead of msi.c so we could do it even without CONFIG_PCI_MSI. Move that to msi.c and fix the config issue with an #ifdef. Then add Vidya's patch on top.
